Sphingolipid metabolism is tightly controlled by enzymes to regulate essential processes in human physiology. The central metabolite is ceramide, a pro-apoptotic lipid catabolized by ceramidase enzymes to produce pro-proliferative sphingosine-1-phosphate. Alkaline ceramidases are transmembrane enzymes that recently attracted attention for drug development in fatty liver diseases. However, due to their hydrophobic nature, no specific small molecule inhibitors have been reported. We present the discovery and mechanism of action of the first drug-like inhibitors of alkaline ceramidase 3 (ACER3). In particular, we chemically engineered novel fluorescent ceramide substrates enabling screening of large compound libraries and characterized enzyme:inhibitor interactions using mass spectrometry and MD simulations. In addition to revealing a new paradigm for inhibition of lipid metabolising enzymes with non-lipidic small molecules, our data lay the ground for targeting ACER3 in drug discovery efforts.

A series of new sorafenib derivatives was designed and synthesized. The antiproliferative activity of the synthesized compounds against human lung cancer cell (A549), human pancreatic cancer cell (PC-3), human leukemia cell (K562), and human hepatoma cell (SMMC-7721) was evaluated by MTT assay. The results revealed that several compounds displayed more significant antitumor activities than commercial anticancer agent sorafenib against SMMC-7721. In addition, compounds 7a, 7g, 7l, 7m, and 7p represented obvious growth inhibition with IC50 values of 1-9 μM against four cancer cell lines, demonstrating more predominant activities against cancer cells as compared to sorafenib. Furthermore, some structure-activity relationships have also been established. Compounds containing indole and benzene ring substituted by halogen showed better activity than sorafenib. Wound healing assay suggested that cells would be targeted on their migratory capacity by 7g, potentially affecting the migration activity of these tumors. The effects of A549 and PC-3 cell apoptosis induced by compound 7g were significantly increased compared with sorafenib. Importantly, the result of western blot assay showed that 7g inhibited cell growth by suppressing the activity of EGFR, especially the expression of p-EGFR (Tyr1068).

Compounds for curing intestinal cancers
-
Paragraph 0037-0038, (2018/03/01)
The invention relates to compounds for curing intestinal cancers. The compounds are obtained by the following steps: 4-chloro-3-(trifluoromethyl)aniline and phenyl chloroformate are subjected to amidation reaction, thus an intermediate is obtained, the obtained intermediate and 4-amino-difluorophenol are subjected to amidation reaction, thus an intermediate is obtained, the obtained intermediate and 4-chloro-N-methyl-2-pyridinecarboxamide are subjected to alkylation reaction, thus an intermediate is obtained, and the obtained intermediate is subjected to salt forming reaction, so that the objective compounds of a general formula shown in the description are obtained. The objective compounds which have the general formula can be used for curing intestinal cancers.
